My series 50 seems to be seeping oil around the oil pan gasket, Has any one changed one of these? Do I need to change the rubber bushings on the bolts? I didn't try tightening them, is that a option? Someone told me that the bushings hold the pan tight and do get weak and then leak ???
Thanks Jason

Yep change the gasket and the isolators assemblies ,they are a little pricey. I don't think you can buy just the isolators from DD they come with the bolt,spacer and isolator as a assembly. You could check with the after market people for isolators only
-
Thanks Cliff, I'll call and see how much they are, I need to change oil so I figured that would be a good time to fix it. Do they get torqued?

Will be needing to deal with the same issue after we return north, so please post your progress regarding this fix.
Thanks

I just called my local DD dealer (Penn Detroit) and the gasket is $37.98 and the isolators are $5.43 each, must not get the bolt with them. Not to bad so i have them ordered.

That is not bad a few years ago the gasket was a 100 bucks and the isolator assemblies were 20 bucks each

I would try tightening them first. This may just solve your problem. These gaskets can also be re-used if you clean them up. New is always better of course.

Those have spacers or bottoming bolts you can only tighten the bolts to a certain point,I had to do my 12.7 series 60 last year with a new gasket and isolators to stop a drip lol the gasket grows when you try and clean one
-
Does the gasket fit in a groove or is it just a flat gasket?
-
Fits in a grove with little tits on it to hold it in place on the newer pans ? is your pan plastic
-
I think it's some kind of Plastic or fiberglass by the sound of it when I tap on the side of it.
-
Check it close for cracks
-
Dang leaky 50 series.... Might as well have the two cycle. At least they don't sound like a bucket of bolts.😊 Make sure to use a torque wrench when tightening bolts.
-
I believe the pan on my early Series 50 is cast aluminum.

Just confirmed tonight that I do have a cast aluminium pan. Anybody know the torque specs for the pan bolts?

Jason, for the love of GAWD, please find the torque specs for this piece in your engine manual.
after you crack or warp it based on casual typing...
Some stuff, you gotta confirm in the religious writings.
It's your salvation?
happy coaching!

They are 18 to 22 ft lbs Jason it's in the lube section (4) of your manual ;D you lucky dog you only have 8 to tighten
-
Thanks Cliff! Is there any particular pattern for tightening them?
BW, I would have definitely looked it up before moving on ;D just figured I would ask first ;D
Thanks guys
-
Yes follow the X pattern beginning in the center of the pan

If only I could stop my oil leaks with a simple oil pan gasket change....my 8v92 is now leaking from literally every side of the block from every hose, orifice, gasket, and groove.

Thoroughly clean engine, then look for leaks shortly after. The air movement in engine compartment makes everything look like it's leaking. You could install a Walker air Sep. They are used a lot on boats to keep engine clean.

Probably all the oil is coming from the top around the blower area unless the re builder decided RTV was the way to go on the gaskets

Could have originally been a marine cast block.
I think DD had a buy one get one free sale back when the Navy stopped using them, they were gov't spec'd to ooze oil in salt atmosphere...too minimize corrosion and reduce painting costs.... :)

Scott, Do like Cliff suggested and clean it up and see where it's coming from, those fans just spread it around and make a little leak look like something major. I hate leaks and try to keep things clean, my old 71 didn't leak much and I hope to get the 50 series the same ;D
